Abstract: Disclosed are a semiconductor device and an electronic system including the semiconductor device. The semiconductor device includes a semiconductor substrate including a plurality of trenches and silicon, a gate electrode positioned on the semiconductor substrate and between the trenches, and a source region and a drain region respectively positioned within the trenches. The source region and the drain region include silicon carbide (SiC) or gallium nitride (GaN), the source region and the drain region each includes a first lightly doped region and a second lightly doped region, and a whole of the first lightly doped region overlaps the second lightly doped region in a direction perpendicular to an upper surface of the semiconductor substrate.
